PAPER-FOLDING MACHINE.

To all whom, it' may concern:

Be it known that I, CHARLES lV. CAUsnY, a citizen of the United States, residing at San Antonio, in the co-unty of Bexar and State of Texas, have invented new and useful improvements in Paper-Folding Machines, of which the following is a specification.

This invention relates to improvements in paper folding machines and has particular application to a machine for folding letters and subsequently depositing such letters within envelops.

ln carrying out the present invention, it is my purposcto provide a machine of the type set forth whereby letters may be rapidly and neatly folded and` subsequently disposed Yithin envelops and wherein the various phases of the folding operation will be carried on in an even and uniform manner without mutilating the paper.

lt is also my purpose to provide a machine of this class wherein the letters after being folded will be neatly and effectively placed within envelops and the latter containing the letters subsequently discharged from the machine so that the envelops containing the letters may be conveyed to any convenient or appropriate place.

Furthermore, l aim to provide a machine of the class described which will be entirely `automatic in action and which will embrace the desired features of simplicity, etliciency, durability and convenience coupled with cheapncss of cost in manufacture and marketing and which when installed may be maintained at a minimum expense. i

lVith the. above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within thescope of the claims.

ln the accompanying drawings; Figure 1l is a top plan view of a machine constructed in accordance with the present invention.

Fig. 2 is a longitudinal sectional view4 ings in detail, the numeral 1 indicates the Specification of Letters Patent.

the opposite ends of the transverse barsbeing appropriately fastened to end pieces 5, 5. lt is conceivable, however, that any other suitable form of supporting frame may be employed. Appropriately fastened to the upper edges of the longitudinal and transverse bars at the point of intersection of such bars and extending laterallyfor outwardly of one side of the longitudinal bars is a plate or the like constituting a table 6 on which the letter or other paper to be folded is placed. rlhis table 6 is formed with a longitudinal slot 7 which extends for the major portion of the length of the table and opens into the ways formed by the longitudinal and transverse bars of the frame, while arranged between the transverse bars et of the frame approximately centrally thereof is a longitudinally extending rod 8 forming a support and guide for the main folders of the machine. These main folders are indicated at 9, 9 and as shown are disposed at the opposite sides of the table 6 and are designed to move toward and away from the table. In the present instance, each main folder 9 is carried by a block 10 formed with a bore through which is passed the'rod 8, and comprises a finger 11 having a base portion 12 provided with downturned edges 13 embracing the opposite sides of the block 10 and formed with apertures alining with a bore in the block to receive a pivot pin 14. Utfset from the base portion and formed integral therewith and disposed in a plane parallel with that of the base portion is the working portion 15 of the finger, while extending outwardly from the opposite side edges of the base por-tion 12 of each finger are lugs 16' resting upon guide strips 17 secured to the inner surfaces' of the transverse bars. ln the present instance, eoiled contractile springs 18, 18 are employed to' hold the fingers in normal position, that is, to say, in a horizontal plane, one end of each spring being secured to the base portion of the respective finger while the opposite end thereof is made fast to the adjacent part of the block carrying the iinger. The top edge portions of the longitudinal bars 2 that are confined between the transverse bars 4 are cut away as at 19, 19 to form what may be termed a folding groove 20 contiguous the adjacent port-ion of the longitudinal slot 7 in the table 6, while adjacent to the opposite ends of the groove 2O and pivotally secured to the inner sides of the transverse bars 4 are shoes 21, 2l provided 'with inclined surfaces 22 merging into the horizontal surfaces of the guide lstrips 17. Thus, when the blocks 1Q, 10 are ioved inwardly or toward one another and the table 6, the lugs 16 on the base port-ions of the fingers of the folders ride along the guide strips 17 and onto the inclined surfaces 22 of the shoes 21 thereby enabling the working portions of the folders to ride up above the groove 2O in the table.

Previous to the folders reaching their limit of inward movement, the lugs 16 ride 0H of the relatively high ends of the shoes 21 and drop onto the guide strips 17 whereby the working portions of the folders drop into the groove 20. The bottom of this groove is preferably formed by a layer of felt or other suitable material 23 which' spans the space between the longitudinal bars at this point and has its opposite ends suitably fastened to the o-uter surfaces ofl such bars.

From the structure so far' described, it.

will be readily apparent that a sheet of paper placed upon the table 6 and spanning the groove 2O will have the intermediate portion thereof engaged by the folders and drawn down into the groove, while the opposite end portions will stand upright or vertically, as clearly illustrated in Fig. 2, thus initiating the folding operation.

Tn order to complete the folding operation, l employ'a. supplemental folder which traverses a path at right angles to the path of movement of the main folders and which intersects the path of travel ofthe main folders at the groove 20. ln the embodiment of my invention selected for illustrative purposes, this suplemental folder is in the form of a substantially rectangular metallic strip 24 having the opposite longitudinal edges thereof adapted for sliding movement within grooves 25 formed in the inner surfaces of the longitudinal bars 1 at one end ofthe table 6, while the working end of the strip constituting the supplemental folder is split vas at 2G to facilitate the folding operation and eliminate mutilation of the paper which might occur if the said end of the strip were'otherwise formed. As clearly shown in the drawings, this supplemental folder is designed to slide back and forth between -the longitudinal bars of the supporting frame and moves across the groove 2O at right angles to the path of movement of the main folders 9, 9 and is also designed to be reciprocated back and forth within the grooves 25 at properly timed intervals with respect t0 the movement of the main folders.

Any suitable mechanism may be employed -for operating the main and supplemental folders. ln the present instance, I employ a driving mechanism of a shaft 27 arranged longitudinally between the longitudinal bars 2 of the main frame at the end of the table 6 with the supplemental folder and having the opposite ends thereof journaled in suitable bearings appropriately,'secured to the main frame. -Upon one end of this shaft is keyed or otherwise fastened a driving pulley 28 belted up to a suitable driving motor, such, for example, as an electric motor 29, while the major portion ofthe shaft 27 between the longitudinal bars of the frame is formed with relatively reversed spiral grooves 30 designed to receive one end of a pin 31 carried by the wall of an opening in a cross head 32, the shaft being passed through the opening in the cross head. This cross head is suitably fastened to the free end of the supplemental folder, as clearly illustrated in Fig. 2. Thus, in the rotary motion of the shaft a continuous re ciprocating or rectilinear movement will be imparted to the cross head 32 and consequently the supplemental folder. Sheave wheels 33 are suitably secured to the end piece 3 at the driving end of the longitudinal e bars of the frame and a sheave 34 is suitably fastened to the inner surface of each end piece 5, 5 of the transverse bars. Depending from the lower edge of each longitudinal bar 2 at the point of intersection of the transverse bars is a bracket 35 carrying a pair of guide rollers 36. Trained over each sheave wheel 33 and the sheave 34 at the respective end of the transverse bars is a belt 37 having the opposite ends thereof secured to the lower side of the supplemental folder below the cro-ss head 32, while one run of each belt is securely fastened to the lower surface of the block 10 of the respective main folder, the belts being passed around the respective guide rollers 3G. When the cross head 32 is at the limit of its outward movement, the main folders 9. 9 are resting upon ythe lower wall of the groove 2O and the sheet of paper being folded has the end portions thereof extending upwardly, while the working end of the supplemental folder is out of the groove 2O and disposed adjacent to one side thereof. ln the continued rotation of the shaft the direction of movement ofl the cross head, and consequently that of t-he'supplemental folder, is reversed so that the working end of the supplemental folder now enters the groove 20 beneath the table 6 and over the mam folders 9, 9. In this movement of the supplemental folder, the adjacent upstanding end portion of the 'paper is folded down abeasoa over the working portions of the main folders and onto the central portion of the sheet of paper while when the working end of the supplemental folder reaches the folding line at the junction of the central portion with the other end portion of the paper, the maint l The supplemental folder in addition to functioning as a folder actsV also as an injector whereby the folded sheet may be deposited within an envelop. The supplemental folder is relatively long as compared with the length of the main folders so that theformer may carry out this dual function, while an envelop magazine 38 is suitably secured to the top edges of the longitudinal bars 2 at the'side of the table 6 opposite from the drivingv shaft 27. This magazine has a portion of the bottom wall thereof dropped as at 38 and at the opposite longitudinal edges of such dropped portion entrance and eXit or discharge slots 39, 39', each of a length corresponding to the width of the supplemental folder, respectively `are formed, while the remaining or elevated portion of the lower wall of themagazine is of a width approximately equal to the width of the flap or tongue of the envelop at its greatest point and in the continued movement of the supplemental folder the working end thereof enters the magazine by way of the entrance slot therein and deposits the folded letter within the envelop and subsequently carries both the letter and the envelop out of the magazine by way of the eXit or discharge slot therein. The envelops, designated at E, are of a length equal to the width of the folded paper and placed in the. magazine with the flaps open and with the address side up, therflaps resting upon the higher portion of the bottom wall of the magazine, while the bodies of the envelops are supported bythe dropped ortion of such bottom wall, as clearly il ust-rated in Fig. 2. Suitable means is provided whereby the bottom envelop is opened to facilitate the passage of the letter and the adjacent end of the supplemental folder thereinto. This means, in the present form of my invention,

f comprises a small rectangular frame 40 one end of which is pivoted upon the rod 8 between the longitudinal bars 3 of the frame i and a block 41 slidablymounted upon abolt bolt being passed through the end bars 4of the frame.' Secured yto this `block 4l is one end of a plate 443 which extends into the en'- velop magazine by way of the Aentrance slot 39 and below the elevated or higher portion of the bottom wall thereof. springs 44 each have 'one end secured to the block 41 and the opposite end fastened to one of the end bars of the rectangular frame 40 and these springs act to hold the plate 43 `normally projected, that is, to say, at its limit` of inward movement within the envelop magazine, while connected to the opposite sides of the block 41 are straps 45 the free ends of which are fastened to the Contractile under surface of the supplemental folder envelop magazine and swung in an upward direction and in contact with the under side of the higher portion of the bottom wall of the magazine incident. to the frame 40 being pivoted upon the rod 8. When the cross head 32 travelsin the opposite or reverse direction, the block 41 on the frame 40 is relieved of the influence of the cross head and the springs 44 react and restore the plate to its normal position thereby sliding the plate into the respective envelop. This action of the plate 43 brings the lower wall of the envelop into` contact with the dropped portion of the lower wall of lthe magazine, while the tongue or flap of the envelop remains in engagement with the higher portion of such wall. Consequentlyfthe envelop is in such a condition as to nicely receive the folded letter forced thereinto by the working end of the supplemental folder. immediately succeeding the movement of the supplemental folder into the envelop, the latter under the action of such folder is carried out of the magazine by way of the exit or discharge slot 39 thereof and may be deposited onto a suitable conveyer or otherwise moved out of the'way of the following rection'of travel of the supplemental folder' is reversed and to avoid withdrawal of the letter from the envelop incident to this reverse movement of the supplemental folder, I employ, in this case, a roller 46 which bears against one swall of the exitor discharge slot of the magazine and 1s held 1n contact therewith by means of tension` chine may be varied or changed to adapt the machine to paper of various widths.

Any suitable or appropriate mechanism may be employed for feeding the sheets to the table for folding.

It will be understood that different forms of driving mechanisms may 'be employed for driving the various folders of the machine and in all cases the folders are, of course, so timed relatively to one another as to operate properly in the di'erent phases of the folding operation. f

While I have herein shown and described one preferred form of my invention by way of illustration, L desire it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims and without departing from the spirit of the invention.
